FRICTION-BUCKLE FOR BELTS, 800.

SPECIFICATION forming part Of Letters Patent N0. 651,812, dated June 12, 1900. Application filed April 4. 1900. Serial No. 11,489. (No model.)

To all whom it may concern.- 7

Be it known that I, HUGO G. KRAUSE, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Friction-Buckles for Belts and other Purposes, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description sufficient to enable those skilled in the art to understand, make, and use the same.

The object of this invention is to obtain a one-part friction-buckle made of bent-up wire of pleasing appearance, of small initial cost, not liable to break or get out of order, easily operated, positive and firm in its action and hold, and easily detached or loosened.

I am aware that two-part friction-buckles made of bent-up wire have been heretofore used for fastening together the ends of a bodybelt, the parts forming the friction-buckle being attached to one end of the belt in such a manner that the other end of the belt is adjustably attached thereto; but so far as I am aware there have been no friction-buckles made of a single piece of wire bent up and arranged to operate substantially as does the buckle embodying my invention.

In the drawings referred to as forming a part of this specification, Figure l is aside elevation of a friction-buckle embodying my invention attached to the ends of a belt. Fig. 2 is a front elevation of such buckle and the ends of the belt. Fig. 3 is a side elevation of the friction-buckle embodying my invention detached from the belt. Fig. at is a front elevation of a modification of the frictionbuckle embodying my invention. Fig. 5 is a side elevation of such modification detached from the ends of the belt shown in Fig. 4. Fig. 6 is a front elevation of an additional modification of the buckle embodying the invention, and Fig. 7 a side elevation of the construction illustrated in Fig. 6.

A reference-letter applied to designate a given part is used to indicate such part wherever the same appears throughout the several figures of the drawings.

To make a one-part friction-buckle embodying this invention, Wire of suitable diameter is wound into a coil in like manner as ordinary coiled-wire springs are wound, with the several turns forming the coil slightly opened. The coil should have a slight spring; but it is not necessary that the wire be of the kind known in the art as spring-wire. From one end of the coil of wire a piece is out, com prising more than one turn, as, say, a turn and three-quarters or nearly so.

In the modification illustrated in Figs. 4 and 5 the ends of the coil are bent inward across the coil so as to meet, or substantially so, and form a bar.

In the modification illustrated in Figs. 6 and 7 the coil is wound so as to be fiattened'on the sides thereof, as is well illustrated in Fig. 6.

A,"Figs. 1, 2, and, 3, is a section of a coil forming a friction-buckle embodying my invention and comprises more than one turn of a wire coil cut therefrom. ct a are the ends of the wire thereof.

B is a belt; 0, a loop extending over the portion of the coil between the ends a a and to one end of the belt to which the friction buckle is attached. To secure the detachable end 6 of the belt B in any adjusted po I sition, such end is passed upward through the center of the coil at a point therein opposite the place where the fiap G is attached thereto, from thence over the top turn of the coil and down between the wires of the coil, as, say, at a, Figs. 1 and 3, and underneath the wire of the lower turn of the coil between it and the belt, as at (L as is well illustrated in Fig. 1. The ends a o. of the coil abut against the sides of the belt B and the coilis thereby prevented from turning in the belt.

It will be observed that the construction of this one-part buckle is extremely simple and inexpensive,being of less cost than even a ring out from a coil, as in such case the wire forming the ring has to be flattened'down,so thatthe ends thereof will abuta-gainst each otheigwhile in the construction herein shown and described the ends (L a are left in their initial position in the coil, so as to abut against the sides or edges of the belt (or against the sides of loop 0) to prevent the buckle from turning in the belt. By constructing the buckle so that it will not turn in the belt or in the loop 0 the end of the belt, which is adj ustably and detachably attached to the buckle and which is frequently made of textile material, as a ribbon, is prea belt, one end whereof is attached to the I vented from coming in contact with any but the smooth part of the wire forming such buckle and will not therefore become frayed or torn.

In the modification illustrated in Figs. 4 and5 the bar D, formed by bending the ends of the wire at old, respectively, brings the ends a a of the wire to abut against each other,

thereby preventing the end of the belt B from becoming frayed or torn as such end is attached,adjusted,or detached from the buckle.

The construction illustrated in Figs. land 5 is slightly more expensive than the constantially the same as in Figs. 1, 2, and 3, Y

the flattening of thesides a a 'being the only change from the construction illustrated in such figures.

. Having thus described my invention, what.

I claim as new, and desire to secure by Letters Patent, is-

1. Afriction-buckle comprising more than i one turn of a wire coil, in combination with friction-buckle, so that the ends of the wire abut against the-sides of the belt, and the turns of the coil being open on the side thereof opposite such attachment to the end of the belt, whereby the other end of the belt may be passed upward within the coil, around the upper turn of thecoil, down between the turns of the coil and out underneath the lower turn of the coil between such coil and the portion of the belt adjacent thereto; substantially as described.

2. A friction-buckle comprising more than one turn of a helically-wound wire coil, in combinationwith a belt, means for attaching one end of the belt to the friction-buckle and .means for protecting the adjustable endof the belt from the ends of thecoil, with the 5 turns of the coil open on the side thereofien- @gaging with the adjustable end of the belt, whereby the adj u-stable end'of the belt may be passed upward within the coil, around; the pp r t n of t o l, wn e wee t e 1 turns of the coiland' out underneath the lowerturn of the coil-betweensuohcoil and the portionof the belt adjacent thereto; substantially as described.
